Thermocouple LGR64-001

in metal housingwirelessbuilt-in transmitter

Overview
The LGR-64 is a temperature and humidity sensor/logger designed for both real-time monitoring and recording/playback applications. In monitoring mode the device transmits measurements to a PC in real time and buffers data when communication is interrupted. In recording/playback mode the logger stores measurements in internal memory for later download to a PC.

Operating modes and key features

• Monitoring – real-time monitoring applications; logger sends measurements to PC in real time and buffers measurements when communication is interrupted.
• Recording / Playback – recorder logs measurements in internal memory for later download to PC.
• IP65 aluminium enclosure (probe excluded).
• Includes ½ wave antenna and SMA RF connector.
• Power supply: AA Lithium Thionyl battery (included) with plug-in connector.
• ILS functions: wakeup from hibernate mode; trigger a measurement outside the set measurement frequency.

Additional physical/operational details
The product is dew-formation resistant and the maximum dew point is reduced to 80°C. RF communication range in open terrain is typically 100 m to 1 km depending on the reception antenna. Time resolution is 1 s and data memory retention is specified up to 100 years.
